The Armored vehicle launched bridge (AVLB) is an assault bridge employed during battles. The existing AVLB has capacity of 70tonnes.How ever a need was identified to increase its Load bearing capacity above 90tonnes along with higher factor of safety while engaged in military operations. This report presents the improved design of AVLB. The ‘I’-Sections installed in design promotes high moment of inertia and stiffness which makes it resistant to bending moment. The web of ‘I’-Sections provides resistance against shear force. The 3D Model of AVLB created in Solid works. And finite element analysis was performed on the model of AVLB to identify the highly stressed components of design for MLC 90 & MLC 100 static structural loads. The Modal analysis using Finite Element Method (FEM) is used to determine mode shapes and this has been accomplished by the commercial finite elements package ANSYS. And all the efforts made to ameliorate the original AVLB to suit for MLC of 90 and 100 tonnes, along with additional safety to AVLB design by considering the factor of safety value greater than 2 and above.
